La Venganza Del Doctor Mabuse / Dr. M schlägt zu (1972)

"La Venganza del Doctor Mabuse" actually is one of Franco's better films of that period with delightfully twisted characters, stunning locations, truly beautiful camera-work and a terrific musical score. The story is of minor importance but it handles about the mean Dr. Mabuse and his accomplices stealing all kind of attributes from a National Research Institute (including female staff members) in order to complete his own, evil mind-control ray. Dr. Mabuse has this impressive and horribly scarred man-monster that kills for him while the entire police force desperately tries to catch him.
